EOS of Neutron Matter and Neutron Star Properties
The Equation of State (EOS) of pure neutron matter at zero temperature is calculated up to five saturation densities within the Brueckner theory with the inclusion of three-body forces. Three different realistic and accurate two-body forces are considered to evaluate the G-matrix effective interaction for nuclear matter. These models are the chiral N3LO, the CD-Bonn and the Argonne V18, which ... إقراء المزيد

Multiplicity distributions of shower particles and target fragments in 7Li–Em collisions at 3 A GeV/c
Multiplicity distributions of shower particles and target fragments in 7Li–Em (emulsion) collisions at 3 A GeV/c are experimentally studied. In the framework of the multisource thermal model, the multicomponent Erlang distribution is used to describe the experimental multiplicity distributions of shower particles, grey fragments, black fragments, and heavily ionized fragments. The correlations between these multiplicities are experimentally reported. With the ... إقراء المزيد

Various flows of black and grey particles produced in Mg-emulsion collisions at 4.5 A GeV/c
Various flow phenomena of black particles (b-particles) and grey particles (g-particles) produced in magnesium-emulsion (Mg-Em) collisions at 4.5 A GeV/c are reported. These flows are directed and elliptic transverse flows (v 1 and v 2) related by the azimuthal angle (phgr), directed and elliptic reaction plane flows (v R1 and v R2) related by the projected angle (ψ) on the ... إقراء المزيد

Unified Description of Event-by-event Fluctuations in Some Global Observables in Nucleus-nucleus Collisions at High Energies
Event-by-event fluctuations in global observables are an important topic in nucleus-nucleus collisions at high energies. These observables include the multiplicity, total transverse energy, mean transverse energy, mean transverse momentum, etc. Fluctuations in different interacting systems have different strengths and shapes. Interacting systems with different incident nuclei and energies are expected to have different fluctuations. Especially, for systems with different interacting ... إقراء المزيد
